Discordia: MagnaExpansion

From BoardGameGeek:

The eagle banners of the Roman legions fly on the banks of the Rhine. While Nero strives for the throne of Imperium Romanum, the Roman settlements on the border of Germania blossom into large fortified cities that are now clearly distinguishable from one another. Trade flourishes and new outposts emerge to protect against raids by Germanic tribes. However, as the cities grow in splendor, so does discord among the rival governors in competition for the glory of Rome. As governor, you have four years to make your city the most impressive. Use your individual advantages and decide whether you want to use the available outposts on the Magna Tiles to forge a strategic alliance to defend against Germanic attacks to reap valuable bonuses. The Discordia Magna expansion contains 6 individual City Maps (player boards) along with the Magna Tiles representing the outposts. -description from designer
